assuming this is the same undergarment from his armor, probably not. Stormtrooper armor undergarments are a "new skin, a tough black body glove that seal[s] itself as [the wearer] climbs in" - source: Twilight Company: Battlefront (new canon book). We can likely presume that this same garment is similar or better now w/ the First Order

Whatever this is, it appears the Picard maneuver could be performed on it, so that gets an upvote. (and adding another picture)
